  1. Hi everyone, New forum user I've been registering in the different Drone forums myself in search for a Checklist App that I could use on my phone instead of printing out paper card for every flight and finally found this App. It seems to be on the Google Play Store only at the moment, no IOS version I could find. Figured I'll share it as my first post Drone Companion - Android Apps on Google Play The interface is pretty slick and intuitive. It also contains decent tips. Most of the them, I've seen them in one form or another on the various drone forum, but it's a good collection in one place. Pretty good to have, when all steps are done, interface update to a "Safe to Fly" and you're good to go Makes you feel like a real pilot doing it's fighter jet checklist (kinda... if you have a lot of imagination ) Enjoy
  2. Hi! I have a question as is describe in the title. I see that there are many types and qualities but for a race drone with an F3 processor is more than enough .. have told me that the F4 is more GPS and photography. I have an CC3D and works very very well for me right now. What do you use? What think about it? Thanks to all!
  3. Located at the Volcani Center campus in Bet-Dagan, near Tel-Aviv, Agricultural Research Organization (ARO) six institutes are responsible for Plant Sciences, Animal Science, Plant Protection, Soil, Water and Environmental Sciences, Agricultural Engineering, and Postharvest and Food Sciences. ARO also operates four research stations, in various parts of the country, and serves as a testing center for agricultural produce and equipment. Israel's Gene Bank For Agricultural Crops is also located on the ARO Volcani Center campus. While encompassing the full range of agricultural research activities, ARO focuses in particular on arid zone agriculture, enabling Israel - a country short of all the resources required for agriculture - to achieve among the highest levels of agricultural output in the world. As an agricultural research center of international standing, ARO each year attracts a large number of groups from abroad, as well as numerous individual visitors. These include academics, heads of experimental stations, representatives of private companies and public officials. ARO maintains particularly close relations with the various international, regional and national institutes involved in the promotion of good agricultural practice and in the increase of agricultural output, and in particular with the U.N. Food and Agriculture Organization (FAO). At Alpha Unmanned Systems we have always believed that our UAV, the SNIPER, could be useful in improving agriculture. From the Volcani Institute they have proven us correct and by buying two of our drone helicopters they have placed themself at the forefront of agricultural innovation. Equipped with a Flir SC-655 infrared camera plus an on-board processing computer, with a 2 hours autonomous flight and a 2.5 Kg payload; both SNIPER units will support the ARO in their precision agriculture researches, with main topics such as hydric stress, diseases detection or soil nutrients optimization. Also we want to emphasize that we will be pioneers in achieving certification for civilian use of unmanned helicopter. Once delivered, corrected and accepted by the Israeli authority all communication systems and manuals, Alpha gave a training program in Spain, Madrid for two pilots of the ARO and two pilots recognized by the Israel Civil Aviation Authority (ICAA) so they can mentor new pilots in their homeland. After making the handover protocol we travelled to Israel, Tel-Aviv to finish the ATP with our client and perform the first flight tests required to achieve certification by the ICAA. The flights were realized at Tel-Gezer which is a well known area due to it's natural park and past history. All both ATP & ICAA requirements were carried out succesfully.
  4. The radio link range is one of the most important aspects in a UAV. How far can we go with a good radio link? What affects this distance? How to increase the link range? are usual questions that concerns to UAV developers and manufacturers. Well this are the main factors that will have influence while achieving the maximum possible distance: - Bandwidth: the rate of data transfer, bit rate or throughput, measured in bits per second (bit/s). - Transmitter power: is the actual amount of power (in watts) of radio frequency (RF) energy that a transmitter produces at its output. - Antenna gain: an antenna's power gain or simply gain is a key performance number which combines the antenna's directivity and electrical efficiency. Normally the higher the gain, the narrowest radiation patter, f.e. a omny antenna has typically 3 to 5 dBis while a patch antenna can have 9 to 18 dBi but the patch antenna like the used in the G-TRACK must be always aiming to the UAV to have good link quality. - Losses: connectors and cables reduces the final output power of the system as it has looses. - Receiver sensitivity: Is the minimum magnitud of input signal required for a good performance of the device. - Fade Margin: Is the minimum margin necessary to ensure a good communication link measured in dBi a desired fade margin is 20 dB. - Path Loss: The losses produced by the attenuation of the signal caused by the distance between the two radios. - System Gain: Final system transmiting power taking into consideration all the installation; is the sume of the following: Transmitter Power + (Transmitter Antenna Gain - Transmitter Cable and Connector Losses) + (Receiver Antenna Gain - Receiver Cable and Connector Losses) + | Receiver Sensitivity | The following example shows an estimation fo the distance that you can achieve using the PCM data link with both ground and air omny antennas: Tx power = 30dBm (equivalent to 1W) Tx antenna gain = 6dBi Tx cable/connector loss = 2dB (typical value for one meter coax cable) Rx antenna gain = 3dBi Rx cable/connector loss = 2dB Rx sensitivity = -108dBm System Gain = [30+(6-2)+(3-2)+108]dB = [30+4+1+108]dB = 143dB. Under this situation we can have maximum path loss of (System gain - Fade Margin) 143 - 20 = 123 dB that in the frequency of 2.4 Ghz is equivalent to 15 Km. A table that shows some Path Loss values can be found below. Distance (Km) Master Height (M) Remote Height (M) Path Loss (dB) 5 15 2.5 116.5 5 30 2.5 110.9 8 15 2.5 124.1 8 15 5 117.7 8 15 10 105 16 15 2.5 135.3 16 15 5 128.9 16 15 10 116.2 16 30 10 109.6 16 30 5 122.4 16 30 2.5 128.8
  5. You just acquired the Alpha Unmanned Systems Power Board (PB) to make your piston engine UAV more reliable thanks to the back up battery while reducing or eliminating the battery care task. But now, which brushless generator should you choose for your UAV? Wich are the right RPMs to achieve the voltage I need? If you made yourself this questions continue reading this article. First of all, we have good news for you, all electric engines can act as motors or as generators, this means that if you apply electric energy to the engine it will give you work, but if you apply work it will give you electricity! This means that any drone electric engine can be used as a generator thats why they can be found at very affordable prices. But let's focus on what's important. In brushless engines there is a constant that will give us the clue to calculate all the necessary parameters to integrate the Power Board (PB) in the UAV. This constant is the Kv, motor velocity constant or the back Electro Magnetic Force (EMF) constant, this value tells us the number of RPMs that will be achieved when applying a certain voltage and is a data that all the manufacturers will provide. Then, having this value and knowing that we need a minimum of 19 input volts to charge the backup battery and that the maximum allowable input voltaje is 30 volts, a nice voltage value to work with would be lets say 24 volts, now assuming that the typical rpms of the propeller of a Fixed Wing SUAS are 9000 rpms we have all the necessary data to define our brushless engine. RPMs = Kv X Voltaje 9000 = Kv X 24 --> Necessary Kv constant is: 375 But what happens if, for example, we can only find a 475 Kv engine, then we would need to increase the rpms of the brushless generator to achieve the same voltage, in that case we can use the transmission between the propeller shaft and the generator to increase the rpms as follows: Necessary rpms are: Kv X Voltaje --> 475 x 24 = 11400 Gears/Pulleys relationship must be: 11400/9000 = 1.26 this means that the generator gear or pulley must have 1.26 times the number of tooths of the one installed on the propeller shaft, f.e. 15 one and 12 the other (12 X 1.26 = 15.12). Now you have all necessary information to integrate your generator and Power Board on your UAV!
  6. Good evening everyone, Does anyone have an info on International Drone Expo in LA this Demember? Is it worth going? What to expect? I wanted to attend Interdrone, however my schedule wouldn't allow me too. So this next expo may be the one I attend. I haven't been to a drone expo before so I do not know what to expect. Any info would be great, thanks. - Wash
  7. Hey y'all! I'm from PR and got started on RC flying about 2 months ago and due to my time availability and lack of people who are willing to help, it has taken me a while to learn. Any tips are more than welcome. I'm also available to anyone that would like too come over to my little island for any type of activities, drone related or not (everything is better with DRONES).
  8. I am enrolled in the Part 107 Ground School. After completing the Weather & Micro-meteorology section in the Quiz section question 10 /25. Why is frost considered hazardous to sUAS operations. Options are 1) Frost decrease lift capacity by changing the aerodynamic shape of the propellers. 2) Frost decreases lift capacity by spoiling the smooth air over the propellers. 3) Frost increases control effectiveness by slowing the airflow. The Quiz marks #2 as the correct answer. I went with #1 According to your lecture in section on icing on page 23 there is the following paragraph (half way through) "In the same way that frost can change the aerodynamic qualities of the propellers, ice can do the same thing" Can you point me to the section in the lecture that provides the explanation for #2 being the correct answer?.
  9. I'm looking for recommendations on an inexpensive drone that can lift a load of 3-5 pounds. Speed isn't an issue, nor is the ability to fly long distances. Thanks for any suggestions.

  14. I am pulling the trigger today, and buying a phantom 3 advanced. prices look pretty similar (I am considering B&h, adorama, Amazon and drone world) i was wondering who you all preferred? Any weird warranty or supply issues? Who is your vendor of choice? thanks!
  15. After 2 weeks without flying due to high winds, I was finally able to go out and shoot at this local fisherman's cove. Had a great time and got some great footage, hope you enjoy ! Check it out below !
  16. In the VDO is my night practicing session during a drone festival at Queen Sirikit convention center, Bangkok, Thailand. It is my first official racing event. I can finished 3-4 laps as required in practice but when the real race comes I mostly did not finished the race. My time per lap is not good too. The best can go under 14 second per lap but my best time is 17 per laps. I learnt that there are many little things that made me not quite ready for an official race such as; not enough normally used-propellers (it's totally differ for 2-3-4 blades), use to same type of propellers all the way, better go early for a few practices before race, prepare for the worst crash and use the equipment that is easy to fix, bring spare parts, add a barrier in the front of your battery (my battery fly out of my drone once by sliding to the front), don't rush at start (for beginner), in racing they required you to have a laps caller in order to confirm the race is complete. And make sure the camera angle will not tilt on an impact. Most of the problems will be solve if you have a drone mechanic with you. And also if you do not crash at all most of the problems will not occurred.
  17. Hello, My name is Brady Koehler I work with the USDA-ARS in Fargo, ND. I am a lead technician for a sunflower drought stress study. The study will take place over the next 2 years. We have small plots that are about 5 acres and want to get as much information on a plant by plant basis if possible. I am most curious about image processing software that can help me get everything below. I have looked at a few places but there are so many out there. What would you recommend? I also would be curious to which drones you like most. I am currently looking at the DJI Inspire or 3DR Solo combined with an infrared camera, thermo camera, and rgb camera which we can mount and remove. Below is a list of everything we want the drone to do: · Plant height and plant count (RGB camera) · Maturity and flower date · Rogue plants · Hybrid phenology · Evaluate leaf and canopy traits · Canopy height · Canopy temperature to determine CWSI · Measurement of canopy light reflectance for determination of NDVI and CWSI. · Data geo-referencing · Temperature · Normalized Difference Vegetation Index (NDVI) · Crop Water Stress Index (CWSI) · Leaf Area Index (LAI) Thanks, Brady

  23. Hey all, This is Brad Spinuzzi with Adrenaline Aerial Imaging Inc. I am president and chief Pilot-In-Command for Adrenaline Aerial Imaging Inc. We primarily do construction, real estate, and industrial photography but, my passion is action and adventure sports of all kinds. I'll film that for fun any day, all day!! I am learning the "artistic" side of photography and working hard to improve my cinematography, piloting, filming, editing etc. My main experience thus far has been cold-weather, back-country filming, high altitude, commercial construction projects, etc. Always looking to learn from anyone willing to pass along some info and of course return the favor. I look forward to meeting you guys. I am very friendly, have a good (but sometimes ornery sense of humor) and willing to work with/for almost anyone. If you're ever in my neighborhood, shoot me an e-mail or give me a call. I'd love to go fly, film, learn, teach, partner, contract, sub-contract, etc. Now enjoy our flagship video, a little film of what I do in my spare time and where my heart is when it isn't raising my "herd" of children. Thanks for checking us out. Sincerely and Respectfully, Brad
  24. I swore I saw a side bar on an email I got from UAV Coach recently about how you may be able to fly commercially legally if you have sent off for your exemption but haven't received it yet. Is this true some how or do I still need to wait another 4 months to get my exemption before I can fly legally? Was I just seeing things? -Joe
  25. Hello, My name is Marc Concialdi and I am interested in purchasing a drone and want to fly one for a business some day. I have my Pilot's license and instrument rating and have been in aviation for years. I have flown toy drones before, but nothing too serious. I would like to know, which drone would be the best for me to make money with? Are there drones out there that are diverse and can help me make money in a variety of areas? I'd like to purchase one so I can register it with the FAA and start flying to make money as soon as possible
